WINDOW SCAFFOLD.

Application filed March 14, 1922. Serial No. 543,698.

of the city of New York, borough of Brooklyn, in the county of Kings and State of New Yorlghat e invented a new and im-' proved Window Scaffold, of which the following is a full, clear, and exact description.

My invention relates to a window scaffold and aims to provide certain new and useful improvements in connection with a device of this character.

It is an object of this invention to pm,

vide a scaffold which may readily be applied to and removed from a window without marring the woodwork of the same, and which will provide an absolute rigid support when in applied position.

It is a further object of this invention to construct a device of the type described which may be associated with different portions of the frame with equal facility, and which when the same is not in use may be stored within a minimum amount of space.

Among further objects of this invention are that of providing a scaffold particularly adapted to be used adjacent frames of windows, and which may be placed in this position by an unskilled operator, and

Further objects of this invention will become apparent in the annexed specification taken in connection with the drawings which latter illustrates a practical embodiment of the same, and in which;

Figure 1 is a transverse sectional view of a window frame and sash associated therewith, and showing my improved scaffold applied to the lower part thereof.

Figure 2 is a similar view but showing the scaffold applied to the upper portion of the window, and taken along the line 22 and in the direction of the arrow indicated in Figure 3.

Figure 3 is an inner face view of the device as illustrated in Figure 2.

Figure 4 is an enlarged fragmentary view of a detail of construction.

Figure 5 is a View taken along the line 5-5 of Figure 4, and

Figure 6 is an enlarged transverse view taken along the line 66 and in the direction of the arrows indicated in Figure 3.

In these views the reference numeral 10 indicates the window frame, mounting the usual sash 11, and providing a ledge portion 12, it being noted that the essence of my PATENT orr es.)

invention consists in the provision. of a scaffold applicable to either the lower or" upper portion of the frame in a manner hereinafter described, so that all parts of the building adjacent to the windowbpen operator,i'suping may be reached by an ported by the said scaffold. 1 v

lYith a view of having the scaffold incorpoi-ate the maximum amount of strength with a minimum amount Of Weight I preferably which inthe embodiment illustrated are arranged to provide a cubicaliscafi'old 13, it being noted in this connection that I preferably, employ bolts 14 for securing the angle irons suitable floor portion 15 is which an operator maystand.

Secured adjacent the upper and inner end of the cubical scaffold 13 are bars 16 which construct the same of angle irons, .7

one to the other, and that a;

provided upon terminate in plate portions 17 as in-VFigure '3, Swingingly attached adjacent the outer lower edgeof the said cubical scaffold are arms 18 in turn supporting ears 19 which are swingingly attached adjacent their outer ends. .This latter structure is provided with a view of insuring a maximum support to the scaffold in that $00 61?- members 20 are secured upon the inner face of the frame 10.:

Also a pair of cables are provided, which 'cables'have hooks 21 secured to their end portions, their bodies being attached to T head pins 22 in such a manner as to divide each cable into a relatively long portion 23 and a short portion 24. is to be applied to the lower portion of the When the scafi old frame, as in Figure 1 it will be seen that the sashes 11 aremoved to their uppermost p0 sition, and the pin 22 is turned so that its head may be inserted through the slot-of the socket members 20, subsequent to which the pins are allowed to swing so that their heads extend transversely to the slot, it being obvious that when the parts are in this position, any accidental from the respective it will be obvious that it will be necessary to utilize the longer portions 23 of the cables, and the hooks secured to the ends of these portions are caused to engage in the open ings of the ears .19 provided for this purpose, it being understood that the foot portions 17 of the bars 16 will bear against the detachment of the pins. socket members is pre cluded. When the parts are thus disposed,

inner face of the frame and serve to additionally brace the scaffold.

"bridged as in Figure 1. Thus it will be understood that the cubical'scafiold will be up b'r dty means of the bracket thus prometres that 'anymovement of the scalfold will be prevented the workmen will be free to utilize the same without any fear of Ho wever, 'ass'nming'that the scaffold is to besupported in the pesition shown in Figures flfgfand 5 itwill be seen that the por- 'tion 23 'of'the cable is detached from the arm. issed the port-ion 2 L thereof is substituted.

Thus itis unnecessary to t'ake up on the cable in 'view of' the fact that the two pornone thereof are of just such a length as to insure a proper tauth'ess when the parts are inthe position "desired. Also, incident to told is to be moved 'to'this position, and are slid d WnwardlyQare otawidth less than the width of'the ledge 12, the" longer leg of the portion 25 may be reversed as in Fig- 'ur'es 2'and'5 to compensate for this difference i'n'length although the bars '16 willremain at the same'length. Fur theras in Fig- 'ure t 'w'illbenoted that the 16 may p the window, the fact that the" sashes 11, whenthe scafalso be formed of two portions 29 and 30 formed with openings through which bolts may be extended so that in the event the spafioldenconnters unusual difiiculty, additions of framework, etc, the bars may be adjusted to compensate for this difference.

From the foregoing it will be understood that all otthe'objects of this invention are accomplished in that the scaffold is adapted for use in virtuallyany" type of window or opening, and will provide a secure support upon which workmen may move Without any fear t'hat'the scaffold is not adequately supported It will also be appreciated that numerous modifications of structure might readilybe resorted to without in the least departing from the scope of my claim; which is scaffold including a platform adapted to" be' positioned outside a window in one of two locations relative to'theheight of the window,'and supporting means for the platform including a bracket, said bracket being adapted in one location of the scaffold to engage the bottom sill of the windqw and in another location of tlie'scaflold' to engage snugly the upper partof'a sliding sash "of said'brac'ket to that end including an 'L-shaped bracket member and means "for attaching said bracket member to the scafl'eld to disposeeithe'r or the'limbs of the L horizontally to adapt the bracket to engage eithensaid sillbrsaid sash at will,
